Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door structures, in particular to a novel vehicle door opening structure. Background Art

[0002] With the rapid development of trucks and high-end commercial vehicles, sliding doors are increasingly used in automobiles. However, the exposed guide rails and system instability cause sliding doors to encounter various mechanical structure coordination and size problems during the development process, and their quality cannot be effectively improved. Now, traditional VAN and MPV models mostly choose to use sliding doors that slide open in the opposite direction of the vehicle's forward direction when choosing the opening form of the rear doors. Because they occupy a small space outside the vehicle after opening, and the effective door opening rate is larger than that of traditional revolving doors, it is more convenient for passengers to get on and off the vehicle. The sliding doors mostly use multiple guide rails and hinges. The sliding doors can be guided by the guide rails, connected by hinges, and slide along the guide rails to open the sliding doors.

[0003] In the prior art, it is difficult to match the sizes of the guide rails and the hinges during use. Any slight deviation in size will lead to insufficient smoothness in opening the door, resulting in jamming or even abnormal noise. If the angle of the middle guide rail is designed to be small, a faster speed is required to close the door to ensure that the door is locked, that is, a large hand force is required to completely close the door. Some car models do not have enough space to arrange the middle guide rail, and the middle guide rail usually needs to be arranged outside the car, which affects the completeness of the overall shape and is not beautiful enough. Utility Model Content

[0004] The purpose of the utility model is to provide a novel door opening structure to solve the problem that a track structure needs to be set in the above-mentioned background technology, which is not only unable to adapt to different vehicle models, but also has poor vehicle aesthetics.
